In addition to its proven advantages, such as the unique double vortex combustion chamber, automatic heat exchanger cleaning, or smoke extraction via open filling shaft door, the log wood boiler firestar is also available with pellets flange. If the use of wood pellets is likely in the future, the log boiler with pellet flange is the perfect solution. If the buffer or heating circuits require heat after burning of all logs, the operation is automatically continued with pellets. firestar De Luxe with pellet flange firestar Lambda with pellet flange PLEASE NOTE: A pellet flange is possible for firestar 20/30/40 8

A range for all requirements... With HERZ T-CONTROL and BioControl 3000 heating circuits, boiler, buffer and solar can be controlled centrally from the boiler.

Heating circuit 1 Heating circuit 2 Solar Hot water storage with solar usage and buffer storage: With this system configuration solar energy is utilised to provide the domestic hot water.

Additional heating circuits such as under floor heating and the radiators are supplied with heat from the buffer tank.

10 A range for all requirements... With HERZ T-CONTROL and BioControl 3000 heating circuits, boiler, buffer and solar can be controlled centrally from the boiler. The control enables a range of application options. The 2 most common cases are shown below. Heating circuit 1 Heating circuit 2 Solar Hot water storage with solar usage and buffer storage: With this system configuration solar energy is utilised to provide the domestic hot water. When the solar input is insufficient to meet the hot water demand, additional heat is taken from the buffer tank. Additional heating circuits such as under floor heating and the radiators are supplied with heat from the buffer tank. Heating circuit 1 Heating circuit 2 Solar Solar heating support and hygienic hot water preparation: With this system configuration the solar energy heats the water in the buffer tank directly. Domestic hot water is provided using a heat exchanger. Additional heating circuits such as under floor heating and the radiators are supplied with heat from the buffer tank. HERZ buffer tank The installation of a buffer tank considerably increases the efficiency of the heating system, especially during periods of partial load. The variable heat loads from the different heating circuits (e.g. radiators and under floor heating) can be met readily from the buffer. A buffer tank is sized to store the energy of an the boiler s maximum heat output. HERZ recommends the following buffer tank sizes for the wood burning boiler: - firestar 18: minimum 1000 Liter (1500 Liter recommended) - firestar 20/30: minimum 2000 Liter - firestar 40: minimum 3000 Liter (Please note the relevant state regulations for buffer storage sizes in order to receive financial support!) HERZ service water storage HERZ offers the optimum solution for service water storage with or without solar register - according to the requirements of the customer. 10
